Just like Jett Dash, you can still bail out of a fight at the click of a button, and you are not restricted by walls like Jett is, allowing you to take fights that she wouldn't normally be able to. The ability is supposed to cut you off from line of sight with the enemy at will. It gives you an insane advantage for peeking aggressively. But because you can only teleport so far, it does NOT guarantee your safety anymore.

Just remember that you're NOT always safe when you TP away, just like how you can still kill a Jett dashing away if they're too aggressive. Playing close angles is way more dangerous now, especially if there is a Neon or Raze who can chase you down. Be cautious of where you can TP.

Most importantly, try to abuse the TP's ability to go through walls and terrain as much as possible. It can make playing close angles completely safe if done correctly (e.g. B Main on Ascent). Get creative!
